On the top side of frame 1, are falenerl helical springs 3, of oppre'iximutely the some inshh diameter as the openings 4', of frame 1; passing" through helical prings 3, and openings 4 oi"? the fi'ouu 1, on": pul- Sators 5, which rest on helical springs 3, hy moons of guards 5, said pnlsators being made of soft rubber of a ihinknons oonsisioni with strength. and (lurahilily and having lhin rubber linings ((36 and i3) which are fastened to ribs 7 in such :1, manner is to form a plurality of convolutions as shown in Figs. 2 and 8 rospvviively. Al" the large P'ml of ezu'h of ihe pulsniors 5. is on opening 8, inlo which is fastened a suitable length of rubber hose 9, each piece of which is connvvlml lo a larger hose. 10, said hose l0,- lining connected to an air-pump which forms no part of my invention and therefore is not shown. Fast-(nod in frame 1 are hrzu-lcvis 1-1. to which are aifnohcri the (Dds oi ssl'rapo 12 and 12, said siraps having elliplir'fll opening; 12. \Vllh'll fit, over ihe hip honv of (he cow, thus; holding the complete apparatus in a fixed position on tho body of the cow.

in order to operate my invonl'ion ii is first necessary to take the 1mlsntors.---ono of which is shown in a flat position in Fig. 1 and huiton said pulsators into lhc shape of a hollowrono as shown in Fig, 3; said opvrntion being performed by folding Hi5 (llllS of Fig. 1 Whivh (-ontnin (he fonuilv u'imnhvrs 1.3, of the olasps, and fastening said lvmalo members 13. to male members ill, of said ulanpx; this living (lone l'he pulsntors urv inocrlwi into their respective pluvis as shown in Figs. 4. and 5, rospoolivoly. Tho next operation is to connect the omzill pivovs of hose 9, to large hose 10. and ihon (-onnool', the hirgo hose 10, lo a suilahlv air-pump, after which the (vomploio apparatus as shown in Fig. 4, is zit-tlu'horl to tho hody of the cow and fastened into place by means of straps 12. and 12. Eaoh ono of tho pulszilors 5, fitting over a foot of (he cow and hold in such position by means of springs i. We are iheu refiuly for tho opeiai'ion oi' millo ingz. 'Wllh'll will he hereinafter fully (ioscribed.

After my invention is iii-mogul tin flivno described. the next operation is; lo pump :ill' into hone 10, from whence il posses inio llusmall pianos oi hose 9, then into oiilighl chambers 15, inflating ruoher lining" (3;

thence passing through port 16, into vhum ber 15*, inflating lining 6. The air then passes through port 16, and into chamber 15 inflating lining 6 The air then passes through port 16", into chamber 15. After this operation the linings are all inflated and take the approximate form of the' inside parts of the human fingers when the hand is closed; as shown in Fig. 2. It is obvious that the above operations cause an even flow of milk from the cow and in no way produce injurious eflects.

With the backward stroke of the pump the linings are exhausted and the upper rims of i pulsators are pressed firmly against the udder of the cow, and the operations of inflating and exhausting are successively repeated until all of the milk is drawn from the cow.

My improved cow-milking apparatu may be constructed of an preferred materizil and made of any size deemed suitable to meet all the requirements of such apparatus, and while I have described a preferred form of cons 'uction and combination of elements cons dered essential in materializing mV in vention, itwill be understood that I desire to include in this application all mechanical equivalents and substitutes that may be considered to come within ,the scope and perview of my invention. 7

Having thus fully described the construction and operation of my invention so that others skilled in the art may be able to construct and use the same, what I-claim as new, and desire to secure by'Iietters Patent is 1. In a cow-milking a 'iparatus a metallic frame with a plurality of circular openings: said metallic frame terminating in a hook which serves as a pail holder; the upper side of said metallic frame having helical springs fastened thereto; pulsators with rubber linings: passing through said helical springs and through the circular openings in said metallic frame: said pulsators being supported by a plurality of guards attached to the outside thereof. and resting on helical springs which hold said pulsators close tothe uddcr of the cow, substantially as described.

2. In a cow-milking apparatus a metallic frame with a plurality of circular openings; said metallic frame terminating in a hook which serves as a pail holder; the upper side of said metallic frame having helical springs fastened thereto; pulsators with rubber linings passing through said helical springs and through the circular openings in said metallic frame: an opening in the upper end of each pulsator to allow the passage of air between the outside texture and the linings thereof; said pulsators being supported by a plurality of guards attached to the outside thereof, and resting on helical springs which hold said pulsators close to the udder of the cow, substantially as described.

3. In a cow-milking apparatus a metallic frame with a plurality 'of circular openings; brackets forming a part of said metallic frame; said metallic frame terminating in a hook which serves as a pail holder; the upper side of said metallic frame having helical springs fastened thereto; pulsators with rubber linings passing through said helical springs and through the circular openings in said. metallic frame; said pulsators being supported by a plurality of guards attached to the outside thereof, and resting on helical springs which hold said pulsators close to the udder of the cow, substantially as described.

4. In a cow-milking apparatus a metallic frame with a plurality of circular openings: said metallic frame terminating in a hook which serves as a pail holder; the upper vside of said metallic frame having helical springs fastened thereto; pulsators with rubber linings passing through said helical springs and through the circular openings in said metallic frame; said pulsators being made flat for convenience in manufacture: means for fastening said pulsators into the form of hollow cones: said pulsatorsbein supported by a plurality of guards attached to the outside thereof, and resting on helical springs which hold said pulsators close to the udder of the cow, substantially as described.

In a cow-milking apparatus a metallic frame with a plurality of circular openings; said metallic frame terminating in a book which serves as a pail holder; thenpper side-of said metallic frame having helical springs fastened thereto; pulsators with rubber linings passing through said helical springs and through the circular openings in said metallic frame: said pulsators being made flat for convenience in manufacture; means for fastening said pulsators into the form of hollow cones: said pulsators being supported by a plurality of guards attached to the outside thereof, and resting on helical springs which hold said pulsators close to the udder of the cow; and means for fastening the metallic frame containing the pu'ltators, to the body of the cow, substantially as shown and described.
